The application program available on the website is only valid for ETS4 or ETS5, is there a compatible version with ETS3?
No, the application program developed for the InZennio Z41 is only compatible with ETS4 or ETS5.
I cannot import the application program for the InZennio Z41, the ETS4 shows the message “The version of the Scheme is not valid", what can I do?
To import the application program for the Z41 is necessary to have the ETS4 software updated with a version of "Scheme" 1.1 or higher. You can view this information from the main screen of the ETS4, in the Overview section. The version information is displayed in the upper right corner.
May I install the InZennio Z41 horizontally?
Yes, from the Z41 Pro/Lite 2.3 versions and Z41 COM 1.1, this touch panels may be installed horizontally or vertically. On the other hand, InZennio Z41 can't be installed horizontally
May I use the KNX bus voltage (29VDC) as the additional power supply of the InZennio Z41?
No, the KNX bus voltage is not a clean signal as it is modulated by the data. This signal can cause a malfunction of the screen.
The KNX bus connector and the external power supply connector are opto-isolated to avoid potential interference with the KNX bus.
Do I need an additional KNX power supply as external power supply for the InZennio Z41?
No, the auxiliary power supply does not need to be a KNX power supply, a conventional power supply (12-29V DC), or the auxiliary output of some KNX power supplies is enough.
What is the total consumption of the InZennio Z41?
The consumption of the InZennio Z41 is divided as follows:
- KNX Bus: 10 mA
- External power supply: the maximum consumption is 150 mA at startup with voltage of 12 V, but in standby, its consumption is reduced to about half of this figure.
What is the firmware of the Z41?, and how can I update it?
We call firmware to the base software preloaded on the device that handles the display of all items on the screen. The firmware is independent of the ETS application program, but both must be the same version for the Z41 to work properly.
The firmware update must be performed via the miniUSB port or the Ethernet port:
- Via USB: using the adapter cable for USB firmware update connected to the mini-USB port placed on the back of the touch screen. The “.PAK” file for firmware update must be copied to the root folder of a USB flash drive.
- Via Ethernet: Downloading de Z41 Update tool and connecting the touch panel to be updated and the computer to the same local network. Z41 Lite cannot be updated via Ethernet
Should I update first the firmware or the software?
Even though it can be done in both ways, from Zennio we recommend to update firstly the firmware version, and secondly the application program.
The screen stays with blue background and it displays an “Error Software” message. What is going on?
The “Error Software” message means a wrong correspondence between Software and Firmware versions.
Software version X.Y must match with the firmware version X.Y.Z. The versions will be compatible when X.Y values are equal.
What is the Ethernet input for?
The Ethernet port built into the InZennio Z41 may be used to upgrade its firmware, and, starting from the version InZennio Z41 3.0 of the application program, for the remote controlling of the InZennio Z41 via IP from devices such as smartphones, tablets, personal computers, etc..
How can I know the Z41 MAC number?
The MAC is displayed on the screen when the touch panel is in the firmware update state.
It is also possible to know it by running the command “arp-a” in the command shell (cmd) of a computer connected to the same network.
If a power failure occurs, do I need to re-set the date and time?
No, thanks to the button battery included in the Z41, the touch panel allows to keep the date and time data after a power failure.
When are the date and time of the Z41 sent to the BUS?
The Z41 Touch Panel only sends the date and time data to the BUS when these two options are set, more specifically when the SET button is pressed, at the end of the manual parameterization.
This feature allows synchronizing the date and time of the rest of Panels in the installation by creating two group addresses “Date” and “Time” to later link them with the appropriate communication objects in the rest of panels to synchronize; this way when adjusting date and time in one of the "master" panels, the rest of them will be also updated.
When having several touch screens Z41 Pro, InZennio Z41 and Z41 Lite in the same installation, How is recommended to configure the time/date sending period?
It is recommended to configure just one screen in the installation to send time and date periodically to the bus, disabling in the remaining devices the parameter “Time/Date Sending Period” that can be found at MAIN CONFIGURATION/ General.
What alphabets can be displayed on the Z41?
Z41 is able to show the following alphabets:
Is it possible to disable the temperature, date and time displayed at the top of the screen?
Starting from the InZennio Z41 version 2.0, Z41 Pro 1.1 and Z41 Lite 1.1, it is possible to disable the display of this information through the GENERAL setting parameters independently.
Can I show a temperature value different from the one measured by the internal sensor in the header of the screen?
This is possible starting from the InZennio Z41 version 2.0, Z41 Pro 1.1 and Z41 Lite 1.1, by enabling this option in the GENERAL setting parameters.
How can I display the values received in an indicator control over time?
Starting from the version InZennio Z41 v2.0, Z41 Pro 1.1 y Z41 Lite 1.1, it is possible to save a log of the values received in indicator controls of 1 or 2 bytes simply by enabling this option via the "Save Log?" parameter. Then, pressing on the indicator will open a pop-up window that will display graphically the values received in this indicator over time.
I have configured an “Energy Monitor” control to display the energy consumption and the objects that I need to link with my energy monitor do not appear. I can only see the objects “Energy Monitor: request” and “Energy Monitor: reset”, why?
To use this “Energy Monitor” control, it is necessary to enable the monitoring channels via the “Energy Monitor Objects” tab that you will find in the MAIN CONFIGURATION section. For each channel, four objects will be created: “Power”, “Energy”, “CO2” and “Cost Estimation”.
I have configured a 2-button control and the value sent by each button does not correspond to its icon. What’s happening?
When configuring the 2-button control, it must be taken into account that the icon selection parameter does not assign functionality to the button. The icon is independent of the value sent.
Starting from version InZennio Z41 v2.0, Z41 Pro 1.1 y Z41 Lite 1.1, all the 2-button controls will have a parameter called "Action" that will allow exchanging the value sent to the bus between the left and right buttons.
I have configured a RGBW control and the object corresponding to the white channel does not appear, I can only see the objects corresponding to the red, green and blue channels, why?
To use the white channel, it is necessary to enable it via the “White Channel Objects” tab that you will find in the MAIN CONFIGURATION section. For each channel, one object will be created: “[RGBW] White Channel”.
Why when playing Scene nº X, the Group Monitor always show a minor number X-1?
This is due to the particular structure of the "Scenes Control" DPT. For further information consult the Scenes Control documentation at our website, available in the Support - Documentation area.
How many Group Addresses do i need to work with Scenes?
One only Group Address will be needed to work with scenes.
Every device involved in the Scene has a specific Communication object "Scenes". It will only be necessary to link this with the "Scenes" Communication Objects in the devices involved in the predefined atmosphere. For further information consult the Scenes Control documentation at our website, available in the Support - Documentation area.
I want to show the current scene in the InZennio?
Scenes are events, not status; while setting a scene, some predefined parameters are set in the devices involved in the same, however these can be later modified by the users.
How can I learn scenes with the InZennio?
Guess a user defines the "Scene Night" (programming the Panel with parameters and group addresses via ETS) to:
- Turn all the lights Off
- Turn Off the Heating and the AC system
- Activate the Alarm System
Once the scene is defined, every time we play it, a predefined atmosphere is generated.
Afterwards, the user wants this configuration instead:
- Turn all the lights Off except one (the one to remain ON, will be a guiding light)
- Turn Off the Heating and the AC system
- Activate the Alarm System
The way to do this is:
1. Run the scene to be modified.
2. Turn the light we want it to be the guiding light On.
3. Just save the new scene into the Panel by keeping a long press (3 seconds) on the original scene "Run" button.
THIS PROCESS REPLACES THE ORIGINAL SCENE BY THE MODIFIED ONE
I have several scenes scheduled to be launched at the same time and only one is launched, why?
Due to the fact that the scene object is unique to the entire touch panel, it is only possible to launch one scene at a time, more precisely, the scene launched will be the one set in the last box of the last page. To avoid this effect, the sending of the scenes can be shifted in time.
How can I schedule a Heating System timer using special modes?
1. Enable Automatic ON when a new special mode arrives in Thermostat configuration and enable Trigger in parameter 1-bit objects working mode in Setpoint configuration.
2. 3 new Communication objects appear for each special mode activation. When sending "1" to any of these objects, the specific Setpoint Temperature is set while an ON order is also sent to the Heating system.
3. Enable four Schedule Programming controls: three controls to send "1" to the corresponding special mode and one more to send the scheduled OFF.
As an example, 4 Group Addresses will be necessary to use the 3 special modes with the Schedule Programming:
- Comfort: with the Comfort object of the thermostat and the timer object of the corresponding control.
- Standby: with the Standby object of the thermostat and the timer object of the corresponding control.
- Economic: with the Economic object of the thermostat and the timer object of the corresponding control.
- OFF: with the ON/OFF object of the climate system and the timer object of the corresponding control.
What is the Technical Alarm Cyclical Monitoring used for?
This function allows a critical alarm system monitoring ( ie gas sensor) to check its proper working in the installation.
The function in this case, waits for a value reception to confirm that the system is working properly. If this value is not received within the specific time parameterized in the ETS, the alarm goes off warning users of a possible problem in the device.
Climate "MODE" Communication object structure in Z41 Touch Panel.
This communication objet (DPT_HVACContrMode_20.105) fulfillls the KNX standard with the following structure:
0 = AUTO
1 = HEAT
3 = COOL
9 = FAN
14 = DRY
This DPT structure is actually implemented in all the Zennio devices, including the IRSC-Plus. This way, all the devices can be integrated together in an installation, as their Communication Objects structure is identical. For further info, please contact our Technical Department.
What is the Special Mode control of the Z41 for?
The Special Mode control is used to set pre-configured setpoints in the thermostat. For further information about this functionality, see the manual of the “Building” thermostat.
Can I restrict the setpoint temperatures in public buildings with the Z41?
Yes, the Z41 temperature controls allow restricting the range of allowed values.
The internal temperature sensor of the Z41 shows a higher temperature value than the real one, Why?
The InZennio Z41 usually gets hot during its programming in such a way that the real temperature is distorted during this time period. The InZennio Z41 will recover the real temperature once it returns to its standby status.
Furthermore, supplying the InZennio Z41 with a voltage value or another can cause variations in the measurement of the temperature; however, the temperature displayed is automatically calibrated by selecting the “Power Supply Voltage” parameter properly.
Additionally, the internal temperature sensor can be calibrated manually from the ETS setup or from the configuration page.
Can the temperature measured by the internal sensor of the InZennio Z41 be sent periodically to the bus?
Yes, within the parameters of the InZennio Z41, it is possible to choose a cyclic sending period of the temperature measured by the internal sensor with a range between 10 and 1000 s.
What kind of thermostatic control does Building Thermostat allow?
In Building Thermostats, the following types of thermostatic control can be configured:
- PI Continuous
- PI PWM
- 2 Points with Hysteresis
What kind of thermostatic control can I use with my climate system?
In a radiators system, thermostat acts over the valves of radiators, which control the hot water circulation through the radiator. If the valves are closed, the hot water from the boiler does not circulate through radiators and after a time they stop radiating heat to ambient. The valves can be:
- Two-points valve (open/close), which can be controlled with 2 Points with Hysteresis or PI-PWM thermostat.
- Motorized valve (percentage), which can be controlled with PI-Continuous thermostat
In radiant floor systems, the thermostat control acts over the valves in the collector return, in the same way that it is done in radiators system. Thus, the same kinds of thermostatic control can be used for radiant floor valves.
In a Fan Coil system, there are two elements to control: valves that allow the water flow through the pipes of the Fan Coil and the fan speed. If a thermostatic control over the valves is carried out, 2 Points with Hysteresis or PI-PWM controls can be used. If the thermostatic control should be applied over fan speed, PI-Continuous control will be the most suitable one.
In zoning systems, a 2 Points with Hysteresis or PI-PWM control acts over the grilles of the different rooms and lets the air of the pump duct get into these rooms until the real temperature in each room reaches its corresponding setpoint.
The PI thermostat demands heat/cool when the real temperature has already reached the setpoint or it does not demand heat/cool when setpoint has not been reached.
When the thermostat performs a PI thermostatic control, the objective is making the real temperature achieve the setpoint temperature, established by user. The PI thermostat calculates the difference between current real temperature and setpoint temperature (proportional part) and also the variation of real temperature during the time that thermostat is activated (integral part). For a correct functioning of the thermostat with a certain climate system, the following characteristics should be bear in mind:
- K and T parameters should be configured according to the climate system that the thermostat is controlling. This way, the thermostat will have into account the thermal inertia of the climate system when calculating the control value.
- Cycle Time for PI control should be selected regarding the thermal inertia of the climate system. The higher the thermal inertia of the climate system is, the longer Cycle Time for PI the thermostat should have.
If these parameters (K, T and Cycle Time) are not correctly selected, the climate system is not responding to thermostat control as expected.
- The climate system should be correctly dimensioned and there should not be an external source of heat/cool different that the climate system. Otherwise, the climate system response to thermostat heat/cool demand could not be the expected and, thus, the thermostat control can be influenced.
For example: a heating system that is under-dimensioned (or it is well dimensioned but the window is open) will not heat as much as the thermostat expects regarding the K and T parameters. The thermostat will calculate a heat demand that the climate system cannot provide. Since the variation of the real temperature is lower than expected, the thermostat will increase the integral part and it will demand more heat. The result is that the climate system takes too long to reach the setpoint temperature and the real temperature will rise several degrees above the setpoint instead of maintaining this temperature.
What is the range of Setpoint Temperature in Building Thermostat?
Zennio Home Thermostat admits Setpoint Temperatures between -20ºC and 95ºC.
Can the thermostat use the temperatures collected from two different temperature probes as reference temperature?
Yes, indeed, when a room is large enough, the temperature can vary in the different sides and it is desirable to collect the temperature from two sources and combine them in one of the following proportions:
- Proportion [75%(1) - 25%(2)]
- Proportion [50%(1) - 50%(2)]
- Proportion [25%(1) - 75%(2)]
Where (1) is the temperature collected from the temperature source 1 and (2) the temperature collected from the temperature source 2.
The KNX controller in installation sends relative Setpoint Temperatures, can I use Zennio Thermostat?
Zennio Building Thermostat allows relative setpoint temperatures, which sets a variation in the setpoint temperature of the active Special Mode, with an Offset. An absolute value of Offset (ºC) can be established with object [Tx]Setpoint Offset or Offset can be incremented or decremented 0.5ºC with [Tx]Setpoint Step.
Setpoint Temperature = Basic Setpoint + Special Mode Offset + Setpoint Offset (variable)
How can I make the thermostat work in Freezing protection mode?
Once the setpoint temperature of the Protection Special Mode is set for Heating Mode in ETS parameters, it works automatically. Whenever the real temperature (reference temperature ot the thermostat) is below the Protection setpoint temperature for Heating Mode, the Heating Control Variable is activated, regardless the thermostat is ON or OFF.
For example: when the Protection setpoint temperature in Heating Mode is 10ºC, the thermostat will send 1 if thermostat is type 2 points with hysteresis or PI-PWM, or 100% if thermostat is PI-Continuous, through the object Heating Control Variable, regardless the thermostat is ON or OFF, whenever the real temperature is below 10ºC.
How can I make the thermostat work in Overheating protection mode?
Once the setpoint temperature of the Protection Special Mode is set for Cooling Mode in ETS parameters, it works automatically. Whenever the real temperature (reference temperature ot the thermostat) is above the Protection setpoint temperature for Cooling Mode, the Cooling Control Variable is activated, regardless the thermostat is ON or OFF.
For example: when the Protection Setpoint for Cooling Mode is 35ºC, the thermostat will send 1 if thermostat is type 2 points with hysteresis or PI-PWM, or 100% if thermostat is PI-Continuous, through the object Cooling Control Variable, regardless the thermostat is ON or OFF, whenever the real temperature is above 35ºC.
What are the special modes?
In Zennio Building Thermostat, the Special Modes are Thermostat Statuses, so that the setpoint for the corresponding Special Mode is established as setpoint in thermostat, but this thermostat setpoint can be changed to fit the user needs.
When the thermostat is OFF, depending on parameter “Automatic ON when a new special mode arrives” in thermostat configuration, it will behave as follows:
- If it is enabled, the thermostat will turn on when a Special Mode is triggered.
- If it is disabled, the thermostat will remain OFF even if a Special Mode is triggered.
How could I know which Special Mode is active?
In Building Thermostat, the active Special Mode can be known through a 1byte object of status [Tx] Special Mode Status.
What is the effect of a setpoint change when a Special Mode is active?
In Building Thermostat, there is always one active special mode:
- Absolute Setpoints: the special mode is maintained if the new setpoint is in the temperature band limited by other special modes setpoints. In case the new setpoint is above or below other special mode setpoint, this special mode is activated.
- Relative Setpoints: the thermostat setpoint is modified but the same Special Mode is maintained. If the setpoint change is due to a change in Basic Setpoint, all the setpoints of Special Modes will be modified. If the change is due to a change in Offset, it will affect to all the Special Modes only if the parameter “Permanently apply change to basic setpoint shift” is enabled. Otherwise, it will only affect to the currently active Special Mode.
Could the setpoint temperatures of the Special Modes be sent to KNX Bus?
When a Special Mode is set, the thermostat setpoint temperature will be updated with the corresponding setpoint of the Special Mode and the thermostat setpoint status will be sent to KNX bus. However, there are not communication objects associated to the setpoints of the Special Modes, so they cannot be read.
How can I select the default values of the setpoint of the Special Modes?
In Building Thermostat, the setpoint temperatures of the Special Modes by default can be selected in the thermostat parameters, with the absolute setpoint of Comfort Mode as a reference and the Offset of the rest of Special Modes.
How can I change the setpoint of a Special Mode?
In Building Thermostat with absolute setpoint, the setpoint of the Special Modes can only be modified if “Permanently apply change to special mode setpoint” is enabled. In this case, before activating the new Special Mode, the current thermostat setpoint is stored as setpoint of the current Special Mode. The setpoint of the special modes can be reset to initial parameterized values, through the Setpoint Reset object. It is also important that the setpoints for Comfort mode cannot be stored if they are below the default setpoint for Comfort in Cooling mode or above the default setpoint for Comfort in Heating mode.
In case “Permanently apply change to special mode setpoint” is disabled, a change in thermostat setpoint is kept until a change of Special mode, but it will not be stored.
In Building Thermostat with relative Setpoints: the setpoints of Special Modes are established with an Offset of Special Mode with Basic Setpoint as reference. If this Basic Setpoint is modified, the setpoints of all the Special Modes will be altered in the same way. The setpoint temperature when a Special Mode is activated will be the default setpoint of the Special Mode in ETS configuration plus the variable Offset value, which is set through the communication object. This variable Offset will affect all the Special Modes if the parameter “Permanently apply change to basic setpoint shift” is enabled. Otherwise, it will only affect to the currently active Special Mode and it will reset (Offset=0) with the Special Mode change.
Offset variation has two important characteristics that should be taken into account:
- The Offset value that can be added to default setpoint will be limited by upper and lower limits, defined in ETS parameterization.
- The Offset change affect to setpoint temperature of the Special Mode in the opposite working mode (Heating or Cooling), so that the automatic change of mode is carried out properly.
How can I synchronize the setpoint temperatures of a Special Mode in different thermostats?
In Building Thermostat with relative setpoints, all the thermostat should have the same parmeters for the offset of Special Modes.
In case “Permanently apply change to basic setpoint shift” is enabled, the setpoint temperatures of the Special Modes can be synchronized with a central control of Basic Setpoint (with objects [Tx]Basic Setpoint) and Offset (with objects [Tx]Setpoint Offset). Otherwise, a central control of Reset (with objects [Tx] Offset Reset) would be needed to set the default Offsets.
In Building Thermostat with absolute setpoints, all the thermostat should have the same parmeters for the setpoints of Special Modes. This way they can be synchronized to default values with objects [Tx]Setpoint Reset, that set de default setpoints.
My thermostat changes between Cooling and Heating mode when I activate a Special Mode
In Building Thermostat, values of setpoints of special modes have a limitation: Comfort, Standby and Economy setpoints should be established according to bands. In addition, the automatic change of mode is caused by variation of real temperature compared with setpoint temperatures of the current Special Mode in Heating and Cooling mode. This avoids undesired automatic changes of mode when a special mode or setpoint temperature changes.
My thermostat always uses 25 ºC as the reference temperature.
The Building thermostat module is independent of the device and it does not use the value measured by the internal temperature probe as the reference temperature by default. It is necessary to create one group address to link the “Temperature Source” object of the thermostat to the sending object of the internal temperature probe or other KNX probe.
Is it possible to establish more than one security code in the InZennio Z41?
It is possible to protect any page of the InZennio Z41 from an unauthorized access. The number of security levels allowed will depend on the application program used:
